.o tetes, and e. iesident of hiontgoineiyj in the eounty oi' Montgomery f; and Starte oi Alebeine., have invented :t new lin Toved Sell-Restoiing Trolley, ol e following is e. hill, elem', sind exec-t Y comino-tor when dis- Ulli.

'retained in posithe usual manner. A LS is mounted loosely upon .vided with s screw or .lon Q. tei'nnnetiing in e disl; l0.

nd eoeentie com 16, simito cylinder S and @ein shaft 6 on the other The Gains il and e shaft that theii4l dommei'dly and iniolley-Wheel. The spyingtlie Wheel le. and the tions, maintenis the n n fixed working rele.- them any perceptible o distei This is easily accomplished, 'oi the .ietiso'n that the :innulei recess 12 is of substantially the seme depth es the springiveshei i3. e Holley-Wheel le and the ser in oontset and yet effe soiling-t ion to eeen other.

o that L L l5 OSL The ooms 11 and 16 move independently of each other end ot the Wheel 14.

My invention used as `follows: It being desired to replztoe the trolley Lipon the conductor, the ti'olley-pole 3 is brought under the Conductor and allowed to iise toweid the seinein the usuel nienner. Either of the sonni poitions 9 l5 being biought into engagement with th nduotoi and the trolley boing moved :ile the trolley-conducto? the spinti 'portion io question tolls against the under side ot the oo nduotoi' until the letter 'is brought into engagement with the one oi the other of the eccentric Cenis il and 16. i single rotation oi eithei beni thus engaged by the eonduetoi forces the trolley-hemp to inove loteolly e. sufficient distance to bring the Wheel le diieotly undei` sind in Contact with the contentos, es will be readily understood tieni ,if 2. Hence the operator, by n x.ii-ily polline trolley-pole downwardly to piece t tiolley-herp beneath the oondnetoi and tl; n releasing the trolleypole. is enabled to sont the om under conditions where he need pay no fui'thei' attention to the trolley. The several petits are in eleo- 'trioel Communication with each other, so that current een be supplied for the purpose of moving the oei, even when the Wheel 14 is out of engagement with the Conductor. The speling-Washer, eddition to the oice ebove described, seives es e eonduoting'member es my invention, claim its new eno. t seem-e by Letters ljetent-- l. in e. tioll y, the combination of s. trolley-harp, e longit'oilinel ineinbei" mounted thereupon, s, ievolnble member mounted upon seid longitudinal ineinbei end piovided with s poi'tion hoving the conformity of an assenti-io eem, another revoluble noembei` mounted upon seid tolley-hai'p and having the conformity oft o soiew, seid revoluble from the revoluble IOO member and trolley-wheelI end free to revolve inde endent of the seid member and wheel for t e purpose of guiding e conductor uponthe trolley-Wheel. g. 3. In e trolley, the vcombination of e trol-I ley-Wheel for engaring a conductor, an ec-vcentric cam -revolu le independently of the trolley-Wheel for engaging said conductor and guiding it upon the trolley-Wheel, anda revoluble cylinder separate from said eccen tric cam and provided with a -ispiral groove for guiding seid conductor to seid cem.

.4. In a trolley, the combination of a trolley-Wheel a cylindrical member provided upon its periphery with a spiral groove, an

I eccentric cam separate from seid cylindrical menber and revoluble independently thereof,"v and, a contct member name to this specification in the the trolley-Wheel and eccentric cam.

g 5. In a trolley,.the combination of a trol- "2o., ley-Wheel, a revoluble cone-shaped eccentric Y =cam independent v,of the trolle f-Wheel mdfl having a smooth peri heral su aceinclinedfb toward; the trolley-w eel, and e revolubl 1 y cylinder independent yof the cam and'ha n' a peripheralsvpirel oove. f A In testimony w ereof .I have signed my f presence of' two subscribing witnesses.
